Code P1244 2011 Ford Fusion Description
The P1244 diagnostic trouble code (DTC) for a 2011 Ford Fusion indicates that the alternator load input has failed high. This means that the powertrain control module (PCM) has detected a higher than normal voltage signal from the alternator load input circuit. The alternator load input is responsible for monitoring the electrical load on the vehicle's charging system, which includes the battery, alternator, and other related components. When the PCM detects a high voltage signal from this circuit, it can indicate a problem with the alternator's ability to properly regulate the electrical output to meet the vehicle's demands.
Common Causes of P1244 2011 Ford Fusion
- Faulty alternator
- Damaged wiring or connectors in the alternator load input circuit
- Malfunctioning PCM
- Defective battery
- Overloaded electrical system
Symptoms of P1244 2011 Ford Fusion
- Dimming or flickering headlights
- Battery warning light illuminated on the dashboard
- Difficulty starting the vehicle
- Electrical system malfunctions, such as power windows or radio not working
- Engine stalling or running rough
How to Fix P1244 2011 Ford Fusion
- Begin by conducting a thorough inspection of the alternator, wiring, and connectors for any visible damage or wear.
- Test the alternator's output voltage and current to determine if it is functioning within the manufacturer's specifications.
- Check the battery's condition and charge to ensure it is not the source of the high voltage signal.
- If necessary, replace the alternator, repair damaged wiring or connectors, or reprogram the PCM to address the issue.
- Clear the DTC from the PCM's memory and test the vehicle to ensure the problem has been resolved.
